If you can get a nice set, go for it. IIRC there are two kinds, the Si version is taller to clear the wiper. Si will fit on a DX/HF, of course, but the reverse is not true.
Funny how your opinions change. I just had to get a set of louvers for my 1G when I bought it new, being the mid-'80s when louvers were all the rage. After a couple years of "Man, these things are a PITA to clean!", I sold them.
If I still had the car, I think it would look cool in a retro way like the other guys have said.
